<title>Introduction to cairo</title>

<para>
|
|
<application>Cairo</application> is a 2D graphics library with support for
|
|
multiple output devices. Currently supported output targets include the
|
|
<application>X</application> Window System, win32, image buffers,
|
|
PostScript, PDF and SVG. Experimental backends include OpenGL, Quartz and
|
|
XCB file output. cairo is designed to produce consistent output on all
|
|
output media while taking advantage of display hardware acceleration when
|
|
available (e.g., through the X Render Extension). The
|
|
<application>Cairo</application> API provides operations similar to the
|
|
drawing operators of PostScript and PDF. Operations in
|
|
<application>Cairo</application> include stroking and filling cubic
|
|
Bézier splines, transforming and compositing translucent images,
|
|
and antialiased text rendering. All drawing operations can be transformed
|
|
by any

|
There is a reciprocal dependency with cairo and libdrm. Best practice is
|
|
to install cairo without the OpenGL backend, and return to re-install
|
|
cairo after the full Xorg installation has been completed. Also note
|
|
that the GTK, Poppler and librsvg packages are also reciprocal. As the
|
|
test suite is currently unreliable, it is best to simply skip it at this
|
|
time.

Note that the tests take a long time to run, many of them fail for unknown

|
reasons and it has been known to cause a kernel panic. <!-- I suspect that
|
|
the panic was due to a bug in the xf86-video-ati driver but I can't be
|

sure as the system locked up hard. cairo-1.12.0 has exposed bugs in other

parts of Xorg https://bugs.freedesktop.org/show_bug.cgi?id=47266 Andy
